T0 (1Z6 "whom it mayconeern Be it known that I, SAMUEL Si-IGAL, a citi-' zen of the United States,.a1icl aresident of New York, in th'e'county of New York and State of New-York, have invented certain new and usefulImprovements in Locks, of Which thei'ollowing. is a specification.

My invention relates to locks and niore particularly to that class of locks known as r rim locks operable l'preferahlylby a pin tumbler"mechanism, and. it has tor one 0t its objects the productionoif a loclr casing having .no'vel means whereby the proper place 011 tlre'door or other closure to which the lock is applied niay he easily detern'uned and Iharked for forming. or boring a hole for reception of theeylinder or pin tumbler mechanism.

Afurther olnect 0t theinventi'on is the produdtion' of a loclg thecasing of which I shall he'supplied With'raised and preferably sharpened letters or Words forming insigniaWhichWill he impressed on or will bite into thewoodiof thedoor or closure to which the lock is applied, ivhiclrinsigni'a shall serve" as" a permanent advertisement cut intothe dodrwvhen"the 'loek casing is appliedto the door, to-assist inpreventing movement or displaceinent'of said casing;

A still further object ot'theini ention is the production of'a detachable and novel o ieratin saindle 'adaoted to connect 'togeth'er the key plug of the lock and the locking mechanism- Within thecasingwvhereby installment of the lock is facilitated irrespective of thethicliness of the door.

Still other and further'olojects'and ad vantages of theinvention will appear froin the accompanying description, the invention consisting in the novel parts and'coinbina. hlOllSfllGlQOf herelnatter'lnore particiilarly described'andthenspecifiediii the claims.

deterring to the several figures-of the drawing 1 indicates a door, preferably of. the swinging type, and 2 the door frame. indicates an annular opening tional tornrot pin tunihler lock cylinder l carrying therein a key plug 5 which is provided, asordinarily. with a slot or opening 6 in the rear end thereof Figs 4:). 7 indicates an end plate which is fastened to said key plug by suitable screws (not shown) and which also provid-zul'u'ith a slot 8 therein connnunicating with said lhe said plate 7 engages. the end or edge of the cylinder i; and prevents forward Withdrawal of said hey ,plug through said cylinder. 9 indicates the usual escutcheon carried on the forward end of the cylinder a and engaging the :lace ot' the 'door while 10 indicatesperforated cars which are prciterahly integral with said cylinder and which are provided with snitaole screws 11 adapted to he threaded therethroup'h. The said cylinder has spreading:

prong-lneuihers 12 hinged thereto which are adapted to he spread outwardly by operation of the screws li and to bite into the wall of the opening- 3 to lock the cylinder from withdrawal from said opening and in proper position therein.

13 indicates my novel connecting spindle which operatively connects the key plug and the locking mechanism Within the loclc'casineto actuate said locking! mechanism when a key is inserted in the plug; from without the door and the key is rotated to rotate said plug and eilect a consequent rotation of said spindle. As is manifest, the length of the spindle used varies depending upon the thickness oi door to which the lock is applied vvell as on other conditions. in most cases it is new neeci-r'u v to provide a spindle ot' long length Wli ,h must he cut oil to the proper length which objection- :Zhle. In other cases at the present time sev- Hextending -through. the door tor receiving a conven eral spindles of varying lengths are supplied with the lock which spindles are provided with headed ends. To fasten or attach a spindle of this character to the key plug, after the spindle of the proper length has been chosen, it has been necessary to remove the end plate 7 and insert the spindle Several spindles of varyinglengths are supplied with the lock and the one of proper length chosen depending on the thickness of the door to which the lock is applied. The said spindle may then be 'detachably connected, to the key plug with expedition and facility by insertion of one of the heads 16 through the slot 8 and into the opening 6 and the pressing of the cam surface of the other head against the end wall of said slot to force the spring arms 15 together, thereby permitting said other head to be forced with a snap action through said slot 8 and into the opening 6 as indicated in Fig. 1. The spindle is thus operative-1y and detachably connected to said key plug and may be removed therefrom only by lateral pressure applied thereagainst to again force the spring arms 15 towards each other and permit one head 16 to first be withdrawn from the slot 8 and then the other head thereof.

The lock casin containin the lockin D b h mechanism is indicated at 17 and is mounted on the door by means of suitable screws (not shown) extending therethroughand through perforated lugs 17 with which said casing is provided. l/Vhen so mounted the end of the casing is preferably flush with the door edge as shown in Fig. 1. Said lock casing is provided with arear cover plate 18, detachably secured thereto to-hide and protect the locking mechanism by suitable screws 19. Said cover plate is provided with an annular opening in which a slotted rotatable plate 20 is non-detachably mounted, the slot of which is adapted to have extend therethrough the end of the operating spindle 13 (see Fig. 2), whereby rotation of said spindle will rotate said plate 20. The inner side of said plate 20 has an actuating finger 21 secured thereto and rotatable therewith and it is provided with a transverse pin 22 fastened to the end thereof and adapted to actuate the lock mechanism. The end wall 23 of the casing 17 is provided with a slot 24 therein.

Mounted in the front wall of the casing naeaaes on the inside of the door is a hollow operating knob 25 the hollow shank of which is indicated at 26 and which is rotatably supported within the casing in any desirable manner forming no part of my present invention. The said shank is operatively connected with the interior mechanism whereby rotation of the knob 25 will project a bolt27 out of the slot 2a of the casing or retract the same within the casing depending on the direction of rotation of the handle. Likewise the bolt may be actuated by means of the proper key inserted within the plug 5 from without the door, the pin 22 being operatively connected with the interior mechanism as previously described.

I have indicated at 28 raised and preferably sharpened letters or other insignia formed on the edge of the lock casing which, when the casing is screwed to the face of the door, are adapted to bite into the wood of the door '2L1'1(l more effectively hold the casing against movement or displace ment. These letters leave an impression in the wood of the door which may in some cases form an advertisement for the lock maker which is discernible if the casing is removed for any reason.

29 indicates the base of the keeper forming an angle piece which is fastened to the edge of the door frame by suitable screws 30. The body of said keeper which is preferably integral with said base is provided with an opening 81 adapted to receive the bolt 27 to lock the door against opening.

When the position that the lock casing is to be screwed or otherwise fastened on the door has been chosen, it is necessary that the annular opening Sin the door for receiving the lock cylinder be: bored or made at the proper relative location as respects the lock casing so that the spindle 13 will be in direct alignment with the slot in the plate 20. The proper location of the opening may be accurately determined by supplying the hollow knob 25 centrally thereof with an opening 32 (see Fig. in alignment with the slot of the plate 20. The lock casing is then held on the door in the desired position and a sharp pointed instrument inserted into the opening 32, through the hollow knob 25, through the shank 26 thereof and through the slot of the plate 20 and an impression marked on or dented in the door by said tool which impression will be the center. of the annular opening for the cylinder. By this means the annular opening for the cylinder mechanism may be accurately made in the door at the proper location irrespeo tive of the chosen position of the lock casing); and the parts of the look, when it is mounted, will have the proper relative position without the necessity of making many measurements which it is usually customary to make to attain the same results.

opening-therein, and a hollow operating knob for actuating said locking mechanism and provided with an opening registering with said first-named opening and accessible from without the casing.

12. In a look, a lock casing containing the locking mechanism and provided with an opening therein, means adapted to extend through said opening for actuating said locking mechanism, and a hollow knob mounted on said casing for also actuating said locking mechanism and provided with an opening therein in alignment with said first-named opening and accessible from without the casing.

13. In a lock, a lock casing containing the locking mechanism and provided with position-determining means, and a keeper provided with means adapted to register with said position-determining means whereby the proper relative position of said keeper as respects said casing may be determined.
